protests in tahrir square. all this comes as we wait to hear from president morsi who's expected to appear on egyptian television, and it could be his appearance as soon as this hour. steve harrigan's in cairo with more. steve? >> reporter: jenna, the protesters are out behind me for the or seventh night in a row, and as you mentioned, part of the u.s. embassy -- the part that deals with the public and visitor -- was shut down today not because the embassy was targeted, but really because of fears of peripheral violence. this whole section of downtown cairo has seen large street protests for the last several days, police and protesters exchanging rocks and tear gas. two buildings on this street were set on fire overnight. those blazes are now out. we are expecting to see egypt's president in a taped television address later today. he'll likely be introducing a new constitution that's being voted on by the assembly now. that constitution can either calm things down here or enflame things further. it really depends what it has to say about the role of islam in people's life in egypt.
